1'0 all whom it may concern; I

Be it known that I, EDWARD F. KUNATH, a citizen of the United States, residingin' Jersey City, in the county of Hudson andSt-ate of 'New Jersey, have invented certain new and useful. Improvements in Type-Writing Machines, of which the following is a specification.

This invention relates to theribbon mechanism of typewriting machines and articular'ly to means for bringing into use ifferent colors of ribbon at will. i

I provide two or more separate ribbons'of different colors and movable independently of one another to cover the printing point.

In the preferred form of the invention, the

ribbons are superposed or placed one in front of another'in front of the platen, and means either ribbon to cover and uncover the printing point during the type strokes while the other ribbon remains idle. l 'l I illustrate my invention as applied to the well ,known Underwood front strike writing machine, in which s ools carrying the usual ribbon are mounte upon vertical axes one at'e'ach side of the printing oint'in front of the platen. Behind said ri bon, I

stretch a short ribbon of red or other special color, which is wound by means of spools placed at the extreme sides of the machine. The short special ribbon may in some cases be endless; and in such a case two other spools are placed at the front of the machine so that theendless ribbon winds around four spools and incloses the usual ribbon and its s ools. Winding means are provided for t e endless ribbon; and I also provide an individual carrier or vibrator for each ribbon, one carrier in front of the other. Said carriers'are shown movable up [and down by means of levers. The latter may be substantially'like those commonlyusedin the Underwood machine, and may be mounted side by side, either lever being called into operation at the typestrokes. ing mechanism includes the usual universal bar frame, which reciprocates at each type stroke. 1 Upon said reciprocating member mount actuators, one for each of said ribbonvibrating levers; said actuators being Shift? able to engage either one or the other lever;-

Means are provided for detaining the actuators in either shift position, .Means are The lev'er-Operatalso provided-whereby the actuators may be held in such a position that neither lever will beoperated, so thatneither ribbon is caused Patented June 1s,19'07.

to cover the printing point at the .type

strokes, this being a convenience when making' stencils. Other objects and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is a perspective view illustrating my inventionapplied to an Underwood? front strike writing machine. Fig. 2 is] a perspectiveview of the duplex'ribbon'actuaton 1 Fig 3 is'a sectional elevation of the machine taken from front to rear. 1 t

Upon -the'front side of a revoluble platen 1 strike types 2 mounted upon type bars 3, the latter being operated by upright levers 4 connected to key levers 5. In front of the platen isthe usual ribbon 6, winding back and forth upon spools 7, 8, the latter mounted on vertical shafts 9, 10, provided with pinions 11 meshing with pinions 12, the latter rigidly connected to ratchet wheels 13op'erated by pawls 14, the latter pivoted, 'u'pon rock-arms 15 fixed upon a rock shaft 16 having an arm 17 and engaging with the latter is a rock arm ISeXtendmgforWardIy from an upright rockingrframe 19 to which is pivoted at 20 cars formed upon'the rear end of a horizontal table orreciprocating frame 21, the latter having fixedupon its front portion a segmentaluniversal bar 22 operating'upon the type bars. As so far described the parts are in'common use upon'said Underwood machine.- I an upstanding carrier 23 loosely connected at 24 to the front end of a lever 25, which is pivoted upon a shoulder screw 26; the latter threaded into a bracket .27.'fixed upon the rear side ofa horizontal shift rail 28 Said lever has an arm 29 extending up, from said pivot 26 and'provided-with a laterally projecting pin 30., whereby the Iever'is opei' i Said ribbon 6 is threaded through ated during the backward and forward movement of said universal bar frame ortable 21, in a manner presently to be explained.

' Inrear of the main ribbon 6,-Istretch a supplemental ribbon 31 of red or other I- special color, which extends between spools 32, 33, pivoted at the extreme sides of the machine, so that the spools, 7, 8, lie between saidspools 32, 33. The latter, it will be untype, and may be provided with any suitable 'derstood, rnaybe of any usual 'or ordinary on the spool shaft 9, meshin with a bevel, gear 38 upon a horizontal sha t 39, which is or ordinary mechanism for winding the ribspools 7, 8, and the endlessrribbon 31 is carried therearoiind, as seen at Fig. 1, so that said ribbon 31 completely inclos'es or surrounds the s ools 7, 8 with "their attached ribbon 6. T e ribbon 31' will be kept taut by. means of a spring 35, which is connected at one end to a fixture and at the other end toa' lever 36, u on which the spool34 is piv- ,ote'd,-so.that t e latter is forced out or me direction to tighten the ribbon 31. v The special ribbon may be caused to feed back and-forth by means of a bevel pinion 37 connected by b'evelpini'ons 39 and 32 with p the spool 32. During the: Winding of the 25' spool 7 the s '001 32 is caused to rotate in one direction, w ile during the unwinding of- 7 the spool 32 is turnedin the opposite direction. It will be understood that spool 32 will be connected to spbol shaft 10, in case it is desired not to use an endless ribbon but to coil the ribbon back and fortlrupon the spools- 32-and 33.

The ribbon 31 is threadedthroug'h a ribbon carrier 40 mounted directly behind the carrier 23, and having ears41 to embrace a fixed vertical guidei42, which in said machine isthe type-guiding post. Said ears- 4\1-.i't will be understood also confine the caifrir 23; The ribbon against lateral Q displacement. r carriers are guided between said; post 42 and a fixed abutment 43; alspring- 44 being 1 provided upon the carrier 40 for pressing oth carriers lightly forward against-sad 0st 42. The carrier 40 is ,pivo tedfat itsower end to a lever 45, similar tojthe lever25 f and alpngside'thereoffand pivoted upon the 1 shoulder 26' and having tendedar'm 46 provide V with a projecting pin 47 whereby it is operated.

pins 40 of the carrier .40 are 'set inline with.

the. forked main. ortion of said 'can ierfto correspond with-t ribbon 31', which extends substantialiy straight across the m'a-chine; while the pins 23 of the'fro'nt carrier 23 are setforward" of the fork of-said carrier, to correspond 'with' the forward and outwarddirection taken by theribbon of the s ools 7, 8'. Thepins '40 are thus well separated from the pins-23 and the carriers move freely up and down inde endently-of. one another. pon j an upstanding bracket 48', secured upon the table'21 b means of screws 49, I

mount-a pair of si'ini ar actuators 50, 51'hav lever or an upwardly ex-f e direction taken by the.

a position,

ing deep vertical slots, 52, 53'to engage respectively'the projecting lever pins 47, 30. Saidactuators are preferably integrahbeing formed upon the ends of a verticarplate 54 upon said plate by shoulder screws 55, which are inserted with a horizontal slot 56 in said vertical plate 54; said slot enabling the ac-' tuators to be shifted or adjusted horizontally across the reciprocating table 21 whereassociated lever pin 47 or 30, so as to vibrate either lever or 25, and he'nce to throwup ,either ribbon 31 or6, to cause the same, to cover the printin point during the operation of the types, whi e the other ribbon remains idle. At Fig. 1 the actuator is shown in:

. engagement with the lever pin 47, and the lever'is' elevated. The arm 29 of the other ilever restsiagainst a stop 57 fixed upon the shift rail 58, said stop serving for both levers when they are idle.

The necessary shifting of the actuators is effected by a link 59, pivoted at 60 to an ear formed upon the actuator member, and extending toward the right-hand side of, the

'machine, being there pivoted at 61 to a bellcrank 62, and vibrating idly about said pivot '61 during the backward and forward reciprocations of the table 21.v From thebellcrank extends forwardly a link 63 to a finger bell-crank '64 mounted at the front of the machine over the key board. By raising the lever 64, the link 63 is thrown back,

the bell crank 62 vibrates, the link 59 is thrown to the left, the actuator 50 is shifted out of engagement with the pin 47,and the actuato'r' 51-is shifted into enga ement with the pin 30 so that the lever 25 Wlll thereafter be-vibrated "during the type strokes, and the ribbpn 6 thrown up to cover the rinting poidhwhilethe ribbon 31 remainsi 1e; To

maintain'the actuators in either position, I-
